Me i'll pick a brainliest !
which ordered pair needs to be removed in order for the mapping to represent a function?

a.) (–3, –4)
b.) (–2, –1)
c.) (1, –3)
d.) (3, 7)

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
